MINERS LAMP.

SPECIFICATION forming part of Letters Patent N0. 787,678, dated April18, 1905.

Application filed October 25, 1904:. Serial N0. 229,971.

To all whom it may concern.-

Be it known that I, FERDINAND KooH, a citi zen of the United States, anda resident of est Hazleton, in the county of Luzerne and State ofPennsylvania, have invented a new and Improved Miners Lamp, of which thefollowing is a full, clear, and exact description.

This invention relates to improvements in miners lamps, the-object beingto provide in connection with a lamp-spout a wick-raiser of 'simpleconstruction and so arranged as to prevent leakage.

I will describe a miners lamp embodying my invention and then point outthe novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a perspective view of a miners lamp embodying my invention.Fig. 2 is a sectional elevation thereof, and Fig. 3 is a perspectiveView of the wick-raiser.

Referring to the drawings, 1 designates the body of the lamp, and 2 thewick-spout thereof having at its under side and near the lower end alongitudinal slot 3. This slot 3 is formed in a depressed portion 4, andarranged within the spout 2 is a tube 5, having near its I upper end alongitudinal slot 6 in line with the depression 4:, and the upper end ofthe tube 5 has teeth 7 which are inclined slightly inward to engage withthe wick material and prevent its downward movement. Mounted to slidebetween the inner tube 5 and the spoutthat is, within the depression 4isa wick-raising bar 8, having a finger-piece9 extended outward throughthe slot 3. Arranged against the inner side of the tube 5 is a plate 10,which is connected to the bar 8 by means of a pin 1l,extended throughthe slot 6. This plate 10 is transversely concaved and has sufficientspring to engage slightly into the wick material, but permitting adownward movement of the plate relatively to the wick, and

the upper end of the plate is curved inward, as indicated at 12, toengage with the wick during the upward movement.

In the operation when it is necessary to project a wick the wick-raiseris to be moved downward, and then upon an upward movement theinwardly-turned portion 12 of the plate 10 will engage in the wick andcause its upward movement with the plate. During the downward movementof the plate the teeth 7 will prevent a downward movement of the wick.

' Having thus described my invention, Iclaim as new and desire to secureby Letters Patent 1. In a miners lamp, a wick-spout havinga longitudinalslot, an inner fixed tube having aslotand provided with inwardly-turnedteeth, a bar mounted to slide between the spout and tube and having afinger-piece extended outward through the first-named slot, awick-engaging plate slidable within the inner tube, and a part extendedthrough the second-named slot and connecting said plate and bar.

2. In aminers lamp, a wick-spout having a longitudinal slot near thelower end, an inner fixed tube having a slot near the upper end, thesaid tube having inwardly-turned teeth at its upper end, a bar mountedto slide between the tube and spout and having a finger-piece extendedthrough the first-named slot, a transversely-concaved plate arrangedwithin the tube and having its upper end curved inward, and a pinextended from said plate through the second-named slot and connectingwith said bar.

3. A miners lamp having a wick-spout provided with a longitudinaldepression having an outwardly-opening slot, a tube fixedly arrangedwithin the spout and having a slot in line with said depression, thesaid tube having inwardly-turned teeth at its upper end, a bar movablein said depression and having a finger-piece extended through thefirst-named slot, a wick-engaging device arranged within the tube, and apin extended through the second-named slot and connecting said platewith the bar.

4. In a minerslamp, awick-spout having'a longitudinal slot near thelower end, a tube fixedly arranged in said spout and having a spout inits upper end, the said tube havingin- In testimony whereof I havesigned my name to this specification in the presence of two subscribingwitnesses.
